Mayfly hatch begins; downtown, bridge lights will be turned off
The 2013 Mayfly hatch has begun. To keep swarms and the resulting mess to a minimum, Hastings Public Works will be turning off lights in the downtown district and on the bridge until the hatch is winding down. The city apologizes for any inconvenience. The city said the hatch should be mostly finished by the time Rivertown Days begins.
Mayflies have a short, one- to two-day lifespan as adults and are attracted to light. Last year, the swarm caused a head-on crash on the Highway 61 bridge. The bridge lights were on at the time, and snowplows had to be called in to clear the insects from the bridge.
